The benefits of the present utility model include:

1. The utility model utilizes high pressure gas in the pressurized gas containers mounted on a indoor ceiling or a wall as the power source to trigger the shooting mechanism, which releases the high pressure gas thus pushes out the bullets in the bullet holes of the shooting head; the bullets in turn pull out the net in a umbrella-like shape to cover and wrap the suspect, make the suspect unable to escape or struggle; therefore capture the suspect effectively, without injuring the police and people around.

2. The ceiling-mounted catcher is not only equipped with a shooting head but also another pressurized gas container, which can release high pressure gas to spray out stimulating substance and color paint from the small containers under it, causing the suspect unable to open eyes, difficult to breathe and subjects to a strong burning pain, thus the suspect fails temporarily to continue the crime, it wins the time for the police to arrive. Even if the suspect breaks the net and escapes, he will be noticed by people due to the significant color paint sprayed on him, providing valuable witness clues for solving the case later. At night, it can also spray fluorescent powder on the suspect, so that the suspect is exposed.

3. For a ceiling-mounted catcher, the shooting mechanism may be electro-magnetic valve triggered type or fuse resistor triggered type; for a wall-mounted catcher, the shooting mechanism may be electric fuse triggered type or hand-held spinning blade cut type, so that security personnel can take down the catcher from the wall and shoot at the suspect with it in hand; therefore, the shooting types of the utility model are various, and each type is simple in structure and easy to use.

4. The control unit of the utility model is designed at a concealed place that is easy to access; therefore, the utility model can trap the suspect quickly and effectively; the utility model can be connected to an internal alarm system in a police station or be controlled in a remote mode by a central monitoring system in financial enterprises.

5. Combined with existing CCTV monitoring systems of the banks, the utility model delivers great deterrent to criminals and can effectively prevent major crime (e.g., robbery, theft) in banks and jewelry stores.
